Biochemical Signaling

Meaning

Biochemical signaling, or cell signaling, is the fundamental process by which cells communicate with each other and respond to their environment through the transmission of molecular messages. This complex communication network involves chemical messengers, such as hormones, neurotransmitters, and growth factors, binding to specific cellular receptors. The resultant cascade of intracellular events dictates virtually all physiological processes, including metabolism, growth, and the maintenance of endocrine homeostasis. Disruptions in this intricate signaling are often at the core of hormonal imbalances and age-related decline.
